Gallons of water are wasted every time you turn on the shower and wait for the water to heat up, taxing the environment and your pocketbook. Go green by conserving water and save money on your utilities at the same time by using the Macaw Handheld Water Saving Spa Shower. On average, 2.5 gallons of water flows per minute in your shower. At that rate, 1 person showering once a day, wasting only 1 minute of shower water, would equal almost 900 gallons per year. Therefore, a family of four would waste over 3500 gallons! The built in ShowerStart technology saves hot water by stopping the flow of water that is usually wasted before you actually get in. When you are ready, simply hop in the shower, pull of the valve cord and let the water flow. After each shower, the valve will automatically reset. We can assure you there was no compromise of comfort or design of this water saving showerhead. With maximum flow rate allowed by law and 5 different spray settings, you can be sure of a cleansing and relaxing experience each and every time. It will attach to any shower arm with an industry standard 1/2" fitting. Chrome finish, solid brass fittings, ABS body and the spray head is 4" in diameter. # Evolve showerhead # PTFE plumbers tape # Installation instructions # User's guide # Pull cord Trickle Mode Evolve's integrated ShowerStart technology prevents expensive hot water from unnecessarily running down the drain before you actually get in the shower. It does this by automatically entering trickle mode once the water reaches bathing temperature, approximately 95F (35 C) and stays there until you pull the chain to resume normal water flow. If the water flowing to the showerhead has reached this temperature, your Evolve showerhead goes into trickle mode the moment you turn it on. This typically happens when users are taking showers within a few minutes of one another. It could also happen if your bathroom became exceptionally hot - above 95 F (35 C). In either event, pulling the chain will resume your showerhead's normal flow if it is in trickle mode when the water is turned on.
